L-Lysine 1000mg Daily - Effective Cold Sore Support

In this review of Nutricost L-Lysine 500mg (1000mg Serving), the bottom line is simple: this is a practical, value-oriented amino acid supplement for people who need a straightforward lysine dose to support immune function and control cold sores. The reviewer found the product best for those wanting an uncomplicated capsule with a clear ingredient profile and third-party testing, and highlights the portability of a two-bottle supply. The single biggest reason to buy is the reliable 1000mg daily serving option that aligns with common lysine regimens.

Key Features

• 500mg per capsule: Provides a predictable amount of L-lysine so users can easily tailor a 1000mg daily serving by taking two capsules.
• 1000mg per serving: Matches common therapeutic recommendations for cold sore control and general amino acid supplementation.
• Non-GMO and gluten free: Minimizes common allergen concerns and suits people avoiding GMOs or gluten in supplements.
• Third-party tested: Offers additional reassurance about purity and label accuracy for consumers who prioritize verification.
• GMP compliant facility: Manufactured in an FDA registered, GMP compliant facility, which supports consistent production quality.
• Two-bottle supply: A larger total capsule count reduces the need for frequent reordering and is convenient for regular users.

Who It's For

This product is well suited for adults seeking targeted support for cold sore prevention or those looking to add an essential amino acid to a daily routine for general immune and skin health. It appeals to people who prefer capsules that are easy to swallow and a clear dosing option of two capsules for a 1000mg serving.

It is less appropriate for those wanting flavored chews, liquid formulations, or multi-ingredient blends that combine lysine with other vitamins. Anyone needing a lower or highly customized dose should consult a clinician, since the capsules are 500mg each and the packaging favors 1000mg serving guidance.
